Trait odbc_api::handles::CDataMut

pub unsafe trait CDataMut: CData {
    fn mut_indicator_ptr(&mut self) -> *mut isize;
    fn mut_value_ptr(&mut self) -> *mut c_void;
}

A type which can be bound mutably to ODBC.

Safety

Care must be taken to only implement this for types which can maintain their invariants then ODBC writes into them.

Required Methods

fn mut_indicator_ptr(&mut self) -> *mut isize

Indicates the length of variable sized types. May be zero for fixed sized types.

fn mut_value_ptr(&mut self) -> *mut c_void

Pointer to a value corresponding to the one described by cdata_type.
